Somehow my message to Nico678 is not visible. Again thanks for the offer, could you please send me the file to kloopy@net.hr or post it here into files?

Thanks again!

Thanks, I tried it already and it didn't help. Something is dead.

All ICs are soldered down so I'll have to be careful with removing them when I locate the dead one. that is why schematic would be of great help. Thanks Nico for offering. Please send it to kloopy@....

Thanks,

I would try a reset first.

If that doesn't work try swapping the op amp chips from one socket to the other. They may be loose in the sockets or the symptoms will move with the chips.
